Apple TV+'s Fountain Of Youth starring John Krasinski and Natalie Portman is now streaming and while it, very clearly, has a great cast, they cannot save it from itself no matter how hard they try. The script is extremely generic, and the plot is very predictable. While Krasinski and Portman have chemistry, it is almost more romantic chemistry than sibling chemistry, which throws the vibe of the film off a bit. The adventure aspect is fun. Honestly, this would have been a hit in the 1990s, but unfortunately it falls flat in 2025.
